features and benefits
The ET-7026 is a multi-function module with 6-channel analog inputs, 2-channel analog outputs, 2-channel digital inputs and 2-channel digital outputs.
It provides various programmable analog inputs (+/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0 ~ 20 mA and 4 ~ 20 mA), and analog outputs (+/-5 V, +/-10 V, 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/output can be programmed to accept current or voltage as input/output depending upon the position of the corresponding jumper.
