SPECIFICATIONS

Control Modes Bandwidth (4-20 mA Driver Units)

On/Off;Time Modulated Proportioning;High Limit with manual reset. Proportioning 3 to 30% - front panel adjustable.

Offset Adjustment (Proportioning Units) Input Power

Manual reset – Manually adjustable within thebandwidth;front panel adjustment. 120, 208, 240 VAC, +10%, -15%, 50/60 Hz field selectable.

Reset Switch (High Limit Model) Thermocouple Lead Length

Reset switch located on front panel.A normally closed remote reset switch may be used on Catalog Number 55-002140-XXX only. Accuracy will remain within specification forthermocouple lead length up to the equivalent of 150 ohms resistance, e.g., 1000ft.(300m) Type J wire.

Vibration Output (SPDT and DPDT Relay)

Meets MIL STD 202D, Method 201A Resistive:10A at 120 VAC, 50/60 Hz or 5 A at 208/240 VAC, 50/60 Hz. Pilot duty:250 VA, 240 VAC maximum. DPDT relay has normally open contacts only.On High Limit model, the relay is energized above set point, and DPDT relay second pole has normally closed contacts only.

Control Stability

The control set points will remain within ±1% of span when the ambient temperature changes from normal room ambient [80ËšF (25ËšC)] to the ambient temperature limits.Control set point will remain within limits stated below with line voltage changes of + 10%, -15% from nominal:On/Off Units:±0.25% of span.Proportioning Units:±0.25% of span at minimum bandwidth, ±1% of span at maximum bandwidth.

Output to Drive Solid State Relay

Non isolated ouput;do not connect to ground. Terminals may be short-circuited without damaging controller.Energized output is 32 VDC maximum with no load and 5 VDC minimum with 200 ohm load. De-energized output is less than 1 VDC.

Lead Break Protection

Ω or greater).In the case of the High Limit model, the relay will energize.All models normally show “up-scale”meter indication in the event of an open thermocouple. The output de-energizes upon an open thermocouple (500k

Output (4-20 mA Driver)

Output is capable of driving a power controller with a 4 to 20 mA reverse acting control signal input. Maximum load resistance is 750 ohms. Non isolated output;do not connect to ground. Instrument is not damaged by shorted output terminals.

Common Mode Rejection

130 dB or greater measured at 60 Hz.Common mode voltage can be up to 240 VAC, 50/60 Hz on the thermocouple.

Output (Solid State Relay)

Zero voltage switching solid state relay mounted on integral heat sink.Opto-coupler provides 2500 V RMS isolation between input and output.Models are available for either 10A or 20A maximum load current at 240 VAC.

Differential (On/Off Units)

0.25% of span, typical.

Case Construction

Molded ABS plastic (Cycolac KJT
® );dust resistant;captive jackscrew for easy removal of unit from case;captive cam fasteners for easy front panel mounting.

Power Consumption

6 Watts maximum.

Ambient Temperature Limits Termination

Operating:32 to 135ËšF (0 to 55ËšC) Storage:-20 to + 165ËšF (-30 to +75ËšC) No.6 screw barrier strip on rear panel;will accept bare wire or No.6 spade/ring terminals (supplied). Solid state relay has No.8 screw terminals.

Indication

Full scale meter.

Weight Pilot Lamp Indication

1 pound, 10 ounces (0.74kg) maximum.Solid state relay units:2 pounds, 6 ounces (1.08kg) maximum. A red pilot LED indicates relay energized.On full scale indication models, a green pilot LED indicates power on.

Dimensions

See Outline Dimensions on next page.

Accuracy (Set Point and Indication)

±1.5% of span (typical)

Cycle Time (Proportioning Units)

Relay Models:10 to 20 seconds, internally adjustable SSR Models:0.3 to 1.0 seconds, internally adjustable.

Bandwidth (Proportioning Units except 4-20 mA Driver Models)

1 to 10% of span.Frontpanel adjustable.
