Product Information
Extended Description
1SVR730840R0600 ABB: The CM-SRS.M1S is a multifunctional current monitoring relay from the CM single-phase monitors range. This monitoring relay operates with a rated control supply voltage of 24 - 240 V AC / DC and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. It provides a RMS measuring principle for DC and AC currents with 3 measuring ranges: 3-30 mA, 10-100 mA and 0.1-1 A. The CM-SRS.M1S offers selection of over- or undercurrent monitoring, open- or closed-circuit operating principle, with or without latching function. The hysteresis is adjustable within a range of 3 to 30 % of the threshold value. The tripping delay and the start-up delay are adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers screw connection technology with double-chamber cage connection terminals.

FAQs
The CM-SRS.M1S operates from 24 to 240 V AC/DC and uses screw terminals for wiring. It provides two SPDT outputs (2 c/o), rated for 250 V and up to 4 A. For single-phase control, connect the supply lines to the device as per the instruction sheet, route the monitored line through the device’s input, and use the SPDT contacts to drive a control circuit or alarm relay. This setup minimizes wiring errors and supports reliable protection logic in machine panels.
The CM-SRS.M1S offers three measuring ranges: 3-30 mA, 10-100 mA, and 0.1-1 A, enabling precise current monitoring across a range of loads. Start-up and tripping delays are adjustable from instantaneous to 0.1-30 seconds, and hysteresis can be set between 3% and 30% of the threshold value to prevent nuisance trips. Use the device’s adjustment potentiometers or menu (per supplier instructions) to configure the threshold, delay, and hysteresis to match your protection criteria.
Yes, the CM-SRS.M1S is designed for DIN rail mounting (TH35-15 or TH35-7.5) and features screw-terminal wiring for reliable connections. Install the relay in a panel within its operating temperature range of -20 to +60 °C, and ensure adequate clearance for ventilation and wiring. The enclosure provides IP50 protection for the housing and IP20 for terminals, supporting robust operation in standard automation environments.
The CM-SRS.M1S carries multiple certifications and declarations, including CE conformity and UKCA, UL/CSA and cULus listings, CCC and CB certificates, and CQC recognition. It also aligns with relevant standards such as IEC/EN 63000, IEC/EN 60255-27, IEC/EN 61000-6-2, and IEC/EN 61000-6-3, ensuring compliance for safety, reliability, and EMI/EMC performance in industrial environments.
Deploying the CM-SRS.M1S reduces downtime by accurately detecting over- or under-current conditions with stable hysteresis, minimizing nuisance trips. Its 24-240 V supply, DIN rail mounting, and screw-terminal wiring simplify installation and maintenance, lowering field service time. With proven electrical durability (AC-12 cycles) and mechanical durability (millions of operations), operators can expect longer mean times between failures and faster fault diagnosis, improving line productivity and overall return on investment.
