tM-P8/tM-PDW8
8-channel Isolated Digital Input Module

~ NEW ~


tM-P8 Wet Contact Source- or Sink-type Digital Inputs tM-PDW8 Dry Contact Source-type Digital Inputs Wet Contact Source- or Sink-type Digital Inputs Photocoupler Isolation Dry Contact and Wet Contact Selectable via Wire Connections All Channels Can Be Used As 16-bit Counters Dual Watchdog Cost-effective Wide Operating Temperature Range: -25 ~ +75°C

Model: tM-P8

Model: tM-PDW8

The tM-P8 off ers 8 channels for digital input, each of which features photocoupler isolation. In addition, digital input can be either sinkor source-type using wire connections and all channels can be used as 16-bit counters. 4 kV ESD protection and 3750 VDC intra-module isolation are also provided.

The tM-PDW8 off ers 8 channels for digital input, catering for both dry and wet contact, with an eff ective distance for dry contact of up to 500 meters. All channels not only feature Photocoupler isolation, but can also be used as 16-bit counters. 4 kV ESD protection and 3750 VDC intra-module isolation are also provided.
