2.2.3.2 Analog output
The RMC provides a single (1) analog output. The AO has a voltage-sourcing diode input voltage pin, a
current sinking pin, a current sourcing pin, and a ground pin. The AO can provide 4-20 mA output
through the sink and source pins. Calibrate the AO from the user interface. For specific pinout
information, see section

2.2.3.3 Pulse input
The RMC provides two pulse inputs (Pulse input, PI). Each PI can accept a variety of input types: 0-5
Vdc TTL input, Open-Collector (Open-Collector, OC), Open-Drain (Open-Drain, OD), or dry switch type
contact. A Schmidt Trigger type gate provides input hysteresis for improved noise protection. Each PI
has a debounce filter configurable from the user interface. For specific pinout information, see section
3.5.5.3 Pulse input pinouts.

2.2.3.4 Digital input and output
The six (6) RMC DI/DO support the configurable input or output modes of operation.
The digital input mode handles up to 30 Vdc. The configurable built-in pull-up resistor reads signals
from devices with dry contact and open collector/drain output types.
The digital output mode provides a MOSFET open drain (OD) type output that sinks up to 2 Adc
current.
