FAQs
The CM-SRS.11P is designed for DIN rail mounting on TH35-15 or TH35-7.5 rails (IEC 60715). It uses screwless push-in terminals compatible with 2x0.5-1.5 mm² conductors, and requires about 8 mm of strip length. This combination supports fast, reliable terminations and straightforward panel layout during installation.
It provides three measuring ranges: 3-30 mA, 10-100 mA, and 0.1-1 A, with a RMS measuring principle suitable for both DC and AC currents. The device offers a 1 c/o SPDT output rated up to 4 A at 230 V and can be powered from 24-240 V AC/DC, enabling flexible integration with most control systems.
Yes. The CM-SRS.11P aligns with CAN/CSA C22.2 No.14, IEC/EN 63000, IEC/EN 60255-27, and IEC/EN 61000-6-2/6-3, with UL 508 listed compatibility. It also supports CE and UKCA declarations, and IP50 housing ensures protection in typical industrial environments, simplifying regulatory approvals for panel builds.
Key benefits include Easy Connect push-in terminals for rapid termination, a compact footprint (22.5 mm wide) suited to dense panels, and DIN rail compatibility that accelerates installation. A sealable transparent cover accessory helps prevent unauthorized changes, while a robust mechanical/durability profile (millions of cycles) supports long service life with minimal maintenance.
Electrical durability is rated for AC-12 at up to 100,000 cycles, while mechanical durability reaches 30,000,000 cycles, supporting steady operation in high‑demand environments. Combined with IP50 housing and wide operating temperature range, the relay remains reliable from installation through ongoing production, reducing replacement costs and downtime.
