I-9K and I-97K series modules are provided for combining a variety of I/O functions within the WP-9000, XP-9000, LX-9000 and LP-9000 programmable automation controllers (PAC). The I-9K series is based on a parallel interface with high communication speed; while the I-97K series is based on a serial interface.




The differences between the two series are listed as follows:

Features

Spring Clamp Terminal Connector

The spring clamp terminal block for the I-9K I/O module connector offers the advantages (anti-vibration, stable clamping and installation easier) relative to screw terminals. Except I-9040/I-9041 modules, the other I-9K modules support spring clamp terminal connector.

I-9K DO Module Power-on Value Function

The digital output power-on value function of the I-9K DO module ensures that the output of the I-9K DO module can be expected and ensures that if the system fails or is reset for any reason, the output will not damage other equipment.

There are 3 power-on modes: deactivated power-on mode, power-on value mode and hold mode. The following is a description of the applicable conditions for each mode. If an exception is encountered that causes boot mode to be activated:

I-9K DO Safe Value

I-9K DO module equips a Hardware Watchdog (WDT) that monitors the operating status of the module. Its purpose is to prevent problems due to host malfunctions, such as situations where the device is affected by noise, or the program is not stable, etc. When the “refresh WDT” function fails and a Watchdog timeout occurs, all output values on the module will be set to the Safe Value state in order to prevent the controlled target from performing any erroneous operations.

I-9K DI Low Pass Filter

Compared to the I-8K DI module, I-9K DI module has the digital input low pass filter function.

Low-pass filter selectable by hardware or software settings

• Setting by Hardware (1ms/5ms/10ms/20ms/40ms/70ms by Jumper select)
• Setting by Software (Set Jumper position to CPU)

The default low pass filter setting of I-9K DI module is Disable, which can be changed to other modes and set the corresponding output value in DCON Utility or PACSDK API.
