Digital mixed module SDM 081

safe digital inputssafe digital outputs2-O

6 safe digital inputs (+24 V DC/3 mA/0.5 ms) 2 safe digital outputs (+24 V DC/2 A) Doubled clock output signal (short circuit proof) SIL 3/PL e, Cat. 4 So that inputs can be tested and crossed circuits can be detected, 2 non-safe signal outputs, TA and TB, are provided. To use the SDM 081 in an application, a Safety CPU module is required. For the S-DIAS system, EPLAN Macros are available for simple integration into the control cabinet Digital Inputs Type - standard Number - 6 Input voltage - +24 V DC (+18-30 V DC) Input current - 3 mA at +24 V DC Input delay - 0.5 ms Cross-circuit detection signal outputs - Yes Digital Outputs Type - standard Number - 2 Short-circuit proof, current limited - Yes Max. total current - 4 A Voltage range - +18-55 V DC Output voltage - +24 V DC Max. Output current - 2 A Mechanical Features Dimensions - 12.5 x 104 x 72 mm (W x H x D) Protection type - IP20 Article Number/Certification Article number - 20-895-081 Standardization/­certification - UL 508 (E247993) SIL 3 according to EN 62061 PL e, Cat. 4 according to EN ISO 13849-1/-2
