4.2.2 Electrical Input Protection
The input circuit is protected against voltage-reversed polarity, voltage
transients, surges, and spikes according to MIL-STD-1275B.
4.2.3 Electrical Interface
There are 3 output-wiring options. These options must be defined at the
factory per the customer order. See
Wiring Option Configurations , page 67
for wiring/terminal diagrams for each option.
Note : Option 3 is the default unless otherwise specified at the time of the
order.
 Option 1: Power, alarm fault relay, 0–20mA (Figure 9)
 Option 2: Power, alarm, fault & accessory relay (Figure 10)
 Option 3: Power, alarm relay, RS-485, 0–20mA, RS-485 RTN (Figure 11)
Note : SIL-2 covers only 0–20mA outputs.
