NOTE: In most cases, a 4-20 mA passive transducer does

not require an external power supply (see Figure 6). In

some special cases, when the module's power is limited, a

4-20 mA passive transducer does require and external

power supply to avoid power consumption from the

module.

Dry Contact: 0.5 mA maximum sense current. Some

current switches that are not true dry contact closures may

not go to zero ohms when the switch is closed. Any

switch which has more than 412 Ohms effective resistance

(0.2V) when closed must have an interposing mechanical

relay when used with G4106 modules.

Procedure

Turn the G4106's power switch OFF.

Terminate the input wiring to the left termination

strip as shown in Figures 5 and 6.

Set the input configuration jumper according to the

type of signal as shown in Figures 5 and 6.

NOTE: The jumper orientation is critical - see

Figure 4. The jumpers are fragile; grip them only

on the sides shown in Figure 4.

Turn the G4106's power switch ON.
