Description
The tM-AD4P2C2 is a multifunction module that includes 4 analog input channels, 2 digital input channels and 2 digital output channels. The module provides a programmable analog input range that includes 2 voltage input channels (±1 V, ±2.5 V, ±5 V, and ±10 V) and 2 current input channels (±20 mA, 0 ~ 20 mA and 4 ~ 20 mA). The analog inputs provide a high overvoltage protection of 120 VDC and an adjustable sampling rate. The module supports sink-type digital output with short circuit protection and the digital outputs can be used as voltage input limit alarms. The digital inputs are source-type and all digital input channels can be used as 16-bit counters. There are options for confi guring power-on and safe digital output values. 4 kV ESD protection and 2500 VDC intra-module isolation are also provided. The tM-AD4P2C2 supports the DCON, Modbus RTU and Modbus ASCII protocols, which can be configured via software.
