M-7028
8-channel Analog Output Module. 12-bit Analog Output. Wide Operating Temperature Range: -25 to +75°C. Modbus RTU
Features
The M-7028 is a 12-bit, 8-channel analog output module. It provides a programmable output range on all analog output channels (0 ~ 5 V, +/-5 V, 0 ~ 10 V, +/-10 V, +4 ~ +20 mA or 0 ~ +20 mA). Each analog output channel can be configured for an individual range and the module also features per-channel open wire detection for the +4 ~ +20 mA output, together with 8 kV ESD Protection as well as 3000 VDC intra-module isolation. Options for configuring power-on and safe values are also included.
