Technical Parameters & Electrical Data

Deterministic Network Bus & Module Interfacing

The internal phototriac optical isolation subsystem provides galvanically isolated control processing between low-voltage PLC pulse output modules and high-power AC distribution lines. Built-in zero cross switching logic enforces deterministic phase firing synchronization, maintaining seamless firmware flash compatibility with external temperature controller PID duty-cycle algorithms.

Field Installation & Wiring Guidelines

Mounting Orientation & Thermal Spacing

Mount the unit vertically on a standard 35 mm DIN rail or secure it directly to a grounded vertical panel surface using M4 screws. Maintain vertical clearance around the integral heat sink to allow natural convection airflow.

Input Loop Wiring

Connect the 12 to 24 VDC control signals from the temperature controller to the input screw terminals, observing correct DC polarity. Keep input wiring separated from power cables.

Load Terminal Wiring

Connect the 3-phase AC power lines and resistive heating elements to the output screw terminals using M4 ring or spade lugs. Tighten terminal screws to a torque range of 1.2 to 1.5 N-m.

Frequently Asked Questions

• What control input voltage range is accepted by the G3PE-235B-3N?

  The input accepts a rated supply of 12 to 24 VDC with an allowable operating range between 9.6 VDC and 30 VDC.

• What is the maximum AC load current rated per phase at 40 deg C?

  The module continuously switches up to 35 A per pole at an ambient operating temperature of 40 deg C.

• What total resistive heater power can be controlled at 200 VAC?

  The maximum 3-phase load carrying capacity supported by the output terminals is 12.1 kW at 200 VAC.

• Does the solid state relay incorporate zero cross firing logic?

  Yes, an integrated zero cross circuit triggers switching at AC sine wave zero-voltage crossings to suppress electromagnetic noise.

• How is electrical isolation achieved between the control input and power load?

  Isolation is provided via a phototriac coupler, preventing high-voltage AC surges from reaching input control circuits.

• What peak single-cycle surge current can the power thyristors handle?

  The output power elements withstand a non-repetitive peak inrush current of 440 A for a single 60 Hz cycle.

• What terminal style is implemented for power line connections?

  The unit utilizes heavy-duty screw terminals equipped with pressure plates for secure wire termination.

• Can this SSR be installed in hot-swap power distribution bays?

  No, input logic and line voltage power must be turned off before wiring or physically replacing the solid state relay unit.
