When an industrial control system needs to handle digital signals, relay-style outputs, voltage measurements, and temperature sensors in one compact module, using several separate I/O devices can increase panel space and wiring. The Exor PLIO04 combines these functions in a single multifunction I/O module for flexible signal acquisition and control.
Exor PLIO04, 10 Channel Multifunction I/O Module
The Exor PLIO04 is a multifunction I/O module that combines 10 digital inputs, 10 digital outputs, and multiple analog input configurations. It is designed for control systems that need to connect different types of field signals without using separate modules for each signal type.
The 10 digital inputs are source active high (+24Vdc) inputs supporting 12 - 30 Vdc and include optical isolation. The module also provides 10 SSR outputs with two contacts, supporting loads up to 30 Vdc and 1.4 A, with optical isolation and output delay time of 5ms max.
For analog measurement, the PLIO04 provides 4 differential or 8 single ended individually programmable channels. These inputs can handle voltage signals as well as temperature measurement using various thermocouple types and PT100 RTD, with external cold junction compensation for thermocouple measurements.
The module also provides an additional group of 4 single-ended analog inputs for voltage measurement. With 12-bit A/D resolution and multiple unipolar voltage ranges, it can be used for connecting compatible analog signals from industrial equipment and sensors.
The PLIO04 is designed for compact industrial installations, with an operating temperature of 0 to 50 °C under vertical installation, IP20 protection, and removable terminal block connectors. Its CE and RCM approvals support use in suitable industrial and residential environments.
