Description
The M-7002 is a Multi-function 16-bit device with 4 differential analog inputs, 5 digital inputs and 4 relay output channels. It uses the Modbus RTU protocol for communication (DCON protocol is an optional setting)
It has programmable input ranges on all analog channels (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0 ~ 20 mA and 4 ~ 20 mA), with shortcircuit and overload protection. Each analog channel can be configured to an individual range (Jumper selectable for voltage or current input.) and has 240 Vrms high overvoltage protection. The sampling rate of M-7002 can be increased by switching to the Fast mode, that uses 12-bit resolution.
The Form A type relay outputs can also be set to be alarm outputs. M-7002 also has 4 kV ESD protection as well as 2500 VDC intra-module isolation.
