D8 Module Discrete I/O Wiring
The eight I/O on the D8 expansion module are individually
configurable via software to be inputs or outputs.
Discrete Outputs
The discrete outputs are solid state relays. When off, they have high
impedance, and when on, they have low impedance (50 Ω max, 25 Ω
typical). The maximum current is 75 mA, and the maximum voltage is
30 V.
Outputs can be wired in either a high-side or low-side configuration.
Because all the outputs share a common, all outputs on the same
module must be wired the same.
When switching inductive loads, place a diode or tranzorb across the
load to protect the switch when it turns off. Otherwise, a voltage spike
in excess of the 30 V rating of the SSR may occur. See the D8 Wiring
topic in the RMCTools help for more details.
Discrete Inputs
The discrete inputs are compatible with 12-24 VDC signals. Because all
the inputs share a common, all inputs on the same module must be
wired the same.
