PLCs, Power Supplies & Others

The Schneider PCR 101 functions as a precision control relay module designed for applications requiring accurate and reliable switching performance. This unit provides isolated contact outputs for interfacing control logic with field devices such as contactors, solenoid valves, and indicator lights. You can depend on this module for consistent operation in industrial automation systems.

Technical Specifications

Precision Relay Configuration

The PCR 101 features 4 independent SPDT relay outputs, each providing both normally open and normally closed contacts. This flexibility allows you to control diverse loads with a single module. You can therefore simplify wiring and reduce component count in your control panels.

Each channel includes a dedicated LED indicator that illuminates when the coil energizes. This visual feedback proves invaluable during commissioning and troubleshooting. Technicians can quickly verify output states without additional test equipment.

Robust Contact Ratings

We equipped the Schneider PCR 101 with heavy-duty contacts rated at 5 A at 250 VAC and 5 A at 30 VDC. This capacity handles most pilot-duty applications directly without intermediate relays. Common loads include motor contactors, solenoid valves, and panel indication lights.

The relay contacts achieve 10 million mechanical operations and 100,000 electrical operations at full load. This longevity ensures years of reliable service in typical industrial applications. You benefit from reduced maintenance intervals and lower lifecycle costs.

Electrical Isolation and Protection

Industrial control systems require isolation between logic circuits and field wiring. The PCR 101 provides 2000 V RMS isolation between coil and contacts, protecting sensitive PLC outputs from voltage transients. This isolation also prevents ground loops that could compromise signal integrity.

The module draws only 0.5 W per channel from the 24 VDC control supply, placing minimal load on system power sources. Low power consumption proves particularly valuable in densely populated panels with limited power budgets.

Physical Design and Installation

Measuring 90 mm x 70 mm x 60 mm and weighing 0.3 kg, the PCR 101 occupies minimal panel space. The compact form factor allows dense mounting alongside other control components. You can mount the module on DIN rail or directly on a panel using the integrated mounting tabs.

Captive clamp screw terminals accept 0.2 mm² to 4 mm² wiring, accommodating most industrial control cables. The terminals feature clear numbering for error-free connections. You can terminate wires quickly without special tools.

Application Versatility

The Schneider PCR 101 suits diverse applications across manufacturing, process control, and building automation. Typical uses include interposing relay functions, load switching, signal isolation, and small motor control. The SPDT contact configuration provides maximum wiring flexibility.

For similar industrial automation components, you might examine the RMS TSG TZ C Static Trip protection device available through equipment suppliers. Both components demonstrate the quality expected in modern control systems.

Environmental Durability

This precision relay module operates reliably in -20°C to +55°C environments, suitable for most industrial facilities. The -40°C to +85°C storage range allows safe transport and inventory stocking. CE, UL, and CSA approvals ensure compliance with global standards for industrial equipment.
