Solid State Relays RJCS1A23D30EPNO

Product catalog summary

Overview: The document provides detailed specifications and operational guidelines for the SOLITRON Midi Current Sensing Solid State Relay (SSR), specifically types RJCS and RJCSR. These devices are designed for industrial heating applications, offering features like integrated current monitoring, zero switching, and over-temperature protection.

Specifications:

Operational Voltage: 230 VACrms to 600 VACrms.
Control Voltage: 4 - 32 VDC.
Rated Current: Up to 50 AACrms.
Isolation Voltage: ≥ 4000 VACrms.
Temperature Range: Operating: -20 to +70ºC, Storage: -40 to +100ºC.

Features:

AC semiconductor contactor with integrated current monitoring.
Zero switching and direct copper bonding technology.
LED indications for supply, control, and alarm status.
Local and remote alarm status with adjustable set-point and time delay.

Alarm and Protection:

Over-temperature protection and alarm output type (NPN/PNP, Normally Open).
Alarm conditions include heater break, over-temperature, over-current, and thyristor short circuit.
Alarm delay adjustable via potentiometer, with non-latching alarm signals.

Operational Guidelines:

Local and remote setup procedures for TEACH, RESET, and TEST functions.
Remote operations can be controlled via PLC with up to 50 devices connected in parallel.
Specific procedures for handling alarms and resetting conditions.

Installation and Mounting:

Ready for DIN-rail or chassis mounting with integral heatsink.
Standard housing dimensions for easy replacement of alternative products.

Connection Examples: The document includes diagrams for connecting the SSR to loads and PLCs, highlighting the importance of common ground and proper sourcing from the same 24VDC supply.

Additional Notes: Specifications are subject to change without notice, and the document includes derating curves and dimensions for panel mounting.

Alarm DELAY time has elapsed, the AlarmDELAY timer is reset. 2.4 Over-temperature orOver-current. This alarm occurs if any oneof following two conditionsis true:1. The device detects aninternal over-temperature condition at any time duringoperation and switches off RJCS 1.3.3 Local TEST In the absence of a signal on the control inputӔ terminal, alocal TEST can be made bypressing and holding the but-ton for 5 seconds. After the redLED flashes 5 times, release the button. The device willswitch ON the loads for 1 sec-ond. This test detects if there isan under-current or heaterbreak alarm condition....

RJCS Example > Let the alarm delay setting be2s (min). If the full load currentis set at 30A, then there will bean alarm condition if the cur- rent is under 26.1A for morethan 2s. (Any fluctutation inthe load current that is pre- sent for <2s will not be sig-nalled this is intended to eliminate false alarms due toshort duration under-voltageconditions on the supply phase). If the control inputgoes off within the 2s, the alarm timer will not be resetprovided the control inputgoes on again within 8s (4x2s).
