Single Phase Solid State Relay – 7100S


Product Description

7100S Solid State Relay

  • 7100S has an optional thyristor short circuit and total load failure alarm. An over-temperature shut down is provided for the 250A fan cooled unit.  An over-temperature alarm is also available. Current range: 16-250A at 45°C
  • Voltage up to 500V
  • Intelligent half cycle firing
  • Suitable for SWIR or resistive loads
  • Over-temperature shutdown for 250A fan cooled units
  • Thyristor short circuit alarm
  • Diagnostic load failure detection
  • Digital communications

For use with short wave infrared (SWIR) and low temperature coefficient resistive loads.

Inputs

These units, with integral heat sinks, can be driven by either DC or AC logic signals.  An analog 4-20mA input is available which gives a linear time proportional output.

The DC logic input can be supplied by a Eurotherm REMIO interface unit which can give intelligent half cycle firing to reduce flicker in SWIR lamps.

Fusing

In all cases the output is zero voltage switching.

Alarms

Diagnostic Load Failure detection is an option which alarms on the loss of one or more parallel heating elements (resistive or SWIR). The sensitivity is one out of six. It is auto-setting via a front panel push button.

Digital communications

The Modbus communications option enables remote control of the unit and interrogation of alarm and firing status.

IDEAL FOR:
  • Ovens
  • Paint Drying
