The ET-7002/PET-7002/ET-7202/PET-7202 is a multi-function module with 3-channel analog inputs, 6-channel digital inputs and 3-channel relay outputs. It provides various programmable analog inputs (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0 ~ 20 mA and 4 ~ 20 mA). Each analog input is allowed to configure a proper range with 240 Vrms high voltage protection. Each analog input can be programmed to accept current or voltage as input/output depending upon the position of corresponding jumper. The ET-7002/PET-7002/ET-7202/PET-7202 is fully RoHScompliant and has qualification for 4 kV ESD protection as well as 2500 VDC intra-module isolation.
