Introduction

I-7000 and M-7000 remote I/O modules provide cost-effective protection and conditioning for various valuable industrial control systems. The product line includes sensor-to-computer,  computer-to-sensor, digital I/O, timer/counter, RS-232 to RS-485 converter, USB to RS-485 converter, RS-485 repeater, RS-485 hub and RS-232/422/485 to Fiber Optics.
 

I-7000 supports the DCON protocol, and M-7000 modules support Modbus RTU and DCON protocols. Many SCADA/HMI software and PLCs support Modbus RTU protocol. It is easy for them to integrate with M-7000 modules.
 

The I-7000 series is a family of network data acquisition and control modules that support DCON protocols. It has the same form factor as the M-7000 series.
 

The M-7000 series is a family of network data acquisition and control modules that support Modbus RTU and DCON protocols. With the Modbus RTU protocol, the module can easily communicate with the most popular SCADA/ HMI software and PLC. It has the same form factor as the I-7000 series.

Programmable Power-on Value and Safe Value

 

The DO and AO modules offer programmable power-on and safe values. When the host watchdog mechanism is activated, the DO and AO outputs are set to the pre-configured safe value.

Advanced DI Functions

DI channel is not only for reading digital input status but also provides several advanced functions in the meanwhile.

DI Latch Function

All DI channels provide a Latch function to retain the high/low events in the internal registers of the module. In general, the host controller polls modules one by one to get all DI status. However, there are occasional unexpected events where a DI channel may generate a very brief pulse signal that could be missed if it occurs outside of the polling time. With the latch function enabled, short-duration signals (>=5 ms) will no longer be lost.
 

Low Speed Counter

The DI module automatically counts the DI signal in the background. The signal under 100Hz can be detected and counted.
 

Overvoltage Protection

Many of our analog input modules provide high overvoltage protection for the analog input channels. When user picks wrong line accidentally or high voltage spike is applied to the analog input terminals, the module will not be broken and can still get the correct readings. This feature improves the reliability, reduces maintenance frequency, and makes the whole system more robust.
 

Over-current Protection

For the current measurement module, the introduction of high currents or voltages into the current loop can potentially damage the module. ICP DAS has enhanced the protection for current measurement to ±120 VDC and ±1000 mA. This enhancement ensures that high currents or voltages within the loop do not harm the current measurement, enabling the entire system to operate normally.
 

Open Wire Detection

The thermocouple, RTD and thermistor sensors are widely used in temperature control applications. If the system can not monitor the open wire status of the sensors, it may be very dangerous and cause large damage to life and property. When the wire of sensor is broken and the controller does not know the open wire status, the system may heat the boiler continuously and result in fire or explosion. Our thermocouple, RTD, thermistor modules provide open wire detection and make the system safer.
 

Virtual Channel to Channel Isolation

The “R” and “Z” versions of analog input modules provide +/-400 VDC virtual channel-to-channel isolation to avoid noise interference from adjacent channels in industrial environments. These modules includes I-7017R, I-7017Z, I-7018R, I-7018Z, I-7019R, and I-7019Z. While it isn't physical channel to channel isolation, there is only a 1uA leakage current between adjacent channels, resulting in minimal and negligible interference.
 

Common Voltage Protection

The typical application is to monitor the charging status of the batteries in series. The voltage of each battery is +10 VDC so the first battery is +10 VDC, the second battery is +20 VDC etc. The differential voltage of the 20th battery is only +10 VDC, while the common-mode voltage is around 200 VDC. If the common-mode voltage of the analog input module is not large enough, then it cannot measure the correct voltage of the battery in charging. ICP DAS analog input modules provide +/-200 VDC high common-mode voltage protection for industrial applications, which can effectively solve the measurement errors caused by insufficient common-mode voltage.
 

ESD Protection

In the industrial environment, there are many noises, spike, electrostatic, etc. If the module is not strong enough, it is very easy to be damaged. The I-7K and M-7K modules all pass +/-4 KV ESD contact and +/-8 KV ESD air tests by static electricity gun in our laboratory. The test procedures follow the IEC 61000-4-2 standard. The components used in ICP DAS modules can suppress and withstand the high voltages defined by the IEC 61000-4-2 standard, thereby protecting the modules from the effects of electrostatic discharge.
 

3000 VDC Isolation

The I-7K and M-7K series have 3000 VDC isolation between the field and the internal logic circuit. This isolation prevents the noise from the field to the internal logic that can damage the module. Users are advised to utilize isolated modules on the RS-485 network to eliminate noise interference from adjacent modules.
 

Dual Communication Protocols

All I-7000 and M-7000 modules use a simple command /response protocol for communication. M-7000 also supports the industrial standard Modbus RTU protocol. The user can use high-level language, such as C, VB, Delphi, and others to write their application programs. Some famous software package can control I-7000 and M-7000 directly, such as LabView, Indusoft, Tracemode, EZ data logger, EZ Prog, etc.

I-7000: supports DCON protocol
M-7000: supports Modbus RTU and DCON protocols

Self-Tuner Inside

"Self-Tuner" is a patented ASIC. It auto-tunes the baud rate and data format in whole RS-485 network, and autohandles the direction of the RS-485 communication line. Since the unique features of this ASIC, the user can implement a very flexible remote I/O configuration via the RS-485 network.

Expandable Network

The I-7510 repeater is not just a regular isolated repeater with its built-in "Self-Tuner" ASIC and features such as 3000V isolation, a maximum speed of 115K, adjustable baud rates, and data formats. Each I-7510 repeater extends the network by an additional 4,000 feet. Users should consider network length and hardware loading effects, utilizing the I-7510 to isolate different groups and prevent high voltages from impacting the entire system through a single communication network.
