Omron’s SR203AM01 serves as a dual-channel safety control relay designed for industrial applications. This component requires an input power supply within the range of ±10% at 50-60 Hz, allowing compatibility with both 24 VAC and DC systems. Energy demands are minimal, approximately 2 W, making it efficient for use in various setups.
The relay supports multiple safety input configurations, offering options for 1 normally closed (N/C), 2 N/C, or 2 PNP inputs, which can integrate with light curtain sensors for enhanced safety measures. The output configuration comprises three normally open (N/O) safety contacts accompanied by one normally closed auxiliary contact, facilitating effective control functions.
In terms of electrical ratings, the AC output capacity is rated at 5 A inductive (AC-15) at 230 V, while it can handle up to 3 A inductive (DC-13) at 24 V. The SR203AM01 ensures reliability with a minimum switching voltage and current of 10 mA and 10 V respectively. Additionally, it withstands surge voltages of up to 2500 V. The maximum response time for drop-out is specified at 15 ms when energized, ensuring prompt operational performance.
For output protection, the module can use fast-blow fuses rated up to 10 A or time-delay fuses of 6 A maximum. The relay can be reset manually in a monitored manner or automatically, depending on application requirements. Its installation is straightforward, designed for mounting on a standard 35 mm DIN rail.
The SR203AM01 has an IP20 rating for connection protection and IP40 for the enclosure, highlighting its adaptability to various environments. Operating temperature range is broad, supported from -5 °C to 55 °C (23 °F to 131 °F), making it suitable for different installation sites.
