Digital Outputs
The DIN Gateway v2 has two local open collector outputs on the module, found on the right
half of the first 6-position terminal block, sharing a GND terminal. These can be controlled
either like any other digital output using the RSD logic table seen above, by writing to registers
on the Gateway (see register table on page 25), or manually in the Gateway itself through the
View Gateway Status Registers
as shown previously.
The open collector output can control a relay when wired as shown below. For technical
assistance on choosing a DIN mounted relay for use with the Gateway, please call SignalFire
technical support.
Supply Voltage
Note: The digital outputs on the gateway have built in protection
and can drive relays and inductive loads directly.

Analog Inputs
The Gateway can take up to 3 passive analog inputs through the second 6-position terminal blocks on
top of the module. Each input has a signal in and ground meant for a 1-5V range. If the input is a 4-
20mA signal, use a high-precision 250Ω resistor from the analog input terminal to ground to convert
the signal to 1-5V.
