Ordinary Locations-

The following ordering options are approved by UL: -01, 02, 03, 20, 21, 22, 23, 24, 25, 26, 27, 30, 31, 32, 33, 34, 35, 36, 37, 38, AN, DP, and HT.

Note: -UL order code must be specified for UL approval. Model 1056 UL configurations are assembled per UL requirements and are marked UL on the unit.

POLLUTION DEGREE 2: Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.

Altitude: for use up to 2000 meter (6562 ft.)

Power: Code -01: 115 VAC ±15% 60 Hz ±6%, 10W; 230 VAC ±15% 50 Hz ±6%, 10 W.

Code -02: 20 to 30 VDC. 15 W.

Code -03: 84 to 265 VAC, 47 to 63.0 Hz. 15 W.

Note: Code -02 and -03 power supplies include four programmable relays

Equipment protected by double insulation

RFI/EMI: EN-61326

LVD: EN-61010-1

Alarms relays*: Four alarm relays for process meas- urement(s) or temperature. Any relay can be config- ured as a fault alarm instead of a process alarm. Each relay can be configured independently and each can be programmed with interval timer settings.

Relays: Form C, SPDT, epoxy sealed

Maximum Relay Current

	Resistive
28 VDC	5.0 A
115 VAC	5.0 A
230 VAC	5.0 A

Inductive load: 1/8 HP motor (max.), 40 VAC

Maximum screw torque for power lead connector and relay terminal blocks is 0.6 N.m

CAUTION

RISK OF ELECTRICAL SHOCK

*Relays only available with -02 power supply (20 - 30 VDC) or -03 switching power supply (84 - 265 VAC)
