features and benefits
The 87026PW is a multifunction module that includes 6 analog input channels, 2 analog output channels, 2 digital input channels, 2 digital output channels.
It provides a programmable input range on all analog input (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0 ~ 20 mA or 4 ~ 20 mA), analog outputs are 16 bit at +/-5 V, +/-10 V, 0 ~ 20 mA or 4 ~ 20 mA and all digital outputs can be set as alarm output.
Each analog input can be configured for an individual range and provides a high overvoltage protection of 240 Vrms.
Voltage and current inputs/outputs are jumper selectable.
