Omega Vehicle Security OM-550 manual Voltage Transducer Inputs, Probes, Probe SET

2.3 INPUTS

As previously discussed, the OM-550 accepts either voltage or thermocouple inputs. The Signals discussed in this section are input through one of the channel connectors on the right side of the OM-550.

2.3.1 VOLTAGE (TRANSDUCER) INPUTS

The Voltage connector used for inputs is a white connector with copper pins.

2.3.2 PROBES

Optional Voltage and Current probe sets are available for the OM-550. They provide a convenient way to connect the OM-550 to voltage or current signals:

PROBE SET

±2 VDC	VOLTAGE
±10 VDC	VOLTAGE
4-20 mA	CURRENT

APPLICATION

connects to signals in the ±2 VDC range connects to signals in the ±10 VDC range converts 4-20 mA loop currents to ±2 VDC signals

For convenience, the OM-550 can be programmed to Scale data. The following table includes m (slope), b (offset) and dp (decimal point) settings for common probe applications:

PROBE	INPUT RANGE	m	b	dp	PRINT RANGE	UNITS
±2 V	±2 VDC	+1.00000	+000000	4	-2.0000 to +2.0000	V*
±10 V	±10 VDC	+0.50000	+000000	3	-10.000 to +10.000	V
	0-10 VDC	+0.50000	+000000	3	00.000 to +10.000	V
	0-5 VDC	+0.50000	+000000	3	00.000 to+05.000	V
	1-5 VDC	+0.50000	+000000	3	+01.000 to +05.000	V
4-20 mA	4-20 mA	+1.00000	+000000	3	+04.000 to +20.000	mA**
