CM-S21-24产品概述
The CM control units will monitor one to four CM switches to category 3 in accordance with EN954-1. A fully monitored system that meets category 3 can be achieved when 1 to 30 plus CM switches are used with the CM control units. The CM-SE expansion module can monitor up to 5 CM safety interlock switches each. Multiple CM-SE expansion modules can be attached to the CM-S41 or CM-S21 control units. The CM control units provide EDM (External Device Monitoring, also called MPCE monitoring) and an Automatic Reset Function. This allows the CM control units to replace a safety relay in most applications. Application: The CM Series is ideal for guard door applications of either sliding or swinging types where an extra level of safety is required. NEMA 6 enclosure enables the CM Series safety interlock switches to satisfy most environmental requirements. The CM-S31 stainless steel version has excellent corrosion resistance. Long Life: The CM Series control units are rated for 10 million actuations. Tamper Resistant: The magnetically coded CM switches are tamper resistant to common magnets. Emergency Stop: Dual Channel NC E-stop input is monitored by the CM-S41 control unit in addition to four CM switches. Inputs: Only CM Series non-contact switches may be used as inputs to the CM control units. Outputs: the CM-S21 and CM-S41 both have 2 NO + 1 NC Aux. Outputs. Conforms to EN954-1, EN1088, EN60204-1, TUV certified, UL and C-UL listed, CE marked.
CM-S21 Control Unit. Power Requirement: 24 VAC. Inputs: Up to two CM non-contact switches. Outputs: 2 NO safety Relay Outputs + 1NC Aux. Relay Output. Reset Mode: Automatic or Monitored Manual.
