Before working on the device, disconnect the power. Please observe the safety regulations of electrical engineering and industrial safety and liability associations. Disregarding these safety regulations may result in death, serious personal injury or damage to equipment. Startup, assembly, modifications, and upgrades may only be carried out by a skilled electrical engineer. For emergency stop applications, the machine must be prevented from restarting automatically by a higher-level control system. Protective covers must not be removed when operating electrical switching devices. In the event of an error, replace the device immediately. Repairs, especially if the housing must be opened, may only be carried out by the manufacturer or authorized persons. Otherwise the warranty is invalidated. When operating relay modules, the operator must meet the requirements for noise emission for electrical and electronic equipment (EN 61000-6-4) on the contact side and, if required, take appropriate measures. 102862_04_en PHOENIX CONTACT 4 PSR-...- 24DC/URD3/4X1/2X2/3 Structure 6 8 7 4 9 2 66 2 6 PS R -U R D 3/ 3 5 8 6 3 6 r ,3 e 0 5 0, 38 w o P 1 2 3 t) 1( K (t) 2 K K 1 K 7 1 Y 4 2 6 8 1 4 6 8 1 4 5 7 1 5 5 8 7 1 5 5 5 8 1 2 APPROVAL K 1 Y 16 15 57 58 24 16 28 38 48 58 66 15 27 37 47 57 65 Serial No. Order No.: 29 81 74 5 48 23 PSR-SPP- 24DC/URD3/4X1/2X2/3 Input: 24 V dc Output: 240 V ac/24 V dc. 6A B300 Pilot duy R300 Pilot duty 47 Serial No. Order No.: 29 81 73 2 15 27 37 47 57 65 16 28 38 48 58 66 PSR-SCP- 24DC/URD3/4X1/2X2/3 Input: 24 V dc Output: 240 V ac/24 V dc. 6A B300 Pilot duy R300 Pilot duty ET 01679 58 K APPROVAL 15 1 PSR-SPP- 24DC/URD3/4X1/2X2/3 PSR-SCP- 24DC/URD3/4X1/2X2/3 1 2 3 4 5 7 3 A 6 3 7 1 Y 4 2 16 1 Figure 3 8 1 6 2 K 2 Y1 57 2 A 5 8 6 3 1 1 /K 48 65 7 2 7 3 A PS R -U R D 3/ 3 A 2 8 1 2 r ,3 e 0 5 0, K 3 K1 47 0 1 7 4 w o P t) 1( K (t) 2 K 2 4 9 5 0 2 A 4 8 7 A 5 6 Structure Metal lock for mounting on the DIN rail COMBICON plug-in screw terminal blocks COMBICON plug-in spring-cage terminal blocks 27-28, 37-38, 47-48, and 57-58: Enabling current paths K1, K2: Input 6 7 8 9 10 Y1: Connection to the DIN rail connector 15-16: Confirmation contacts Off delay setting A1, A2: Supply voltage connection 65-66: Alarm contacts Function When the 24 V DC operating voltage is applied at terminal blocks A1-A2 or is led via the DIN rail connector, the "Power" LED lights up. When a 24 V DC voltage is applied at input K1-K2 (or via the DIN rail connector), both relays are activated. The LEDs light up and the contacts for enabling current paths 27-28, 37-38, 47-48, and 57-58 close. Alarm contacts 15-16 and 65-66 open. If the voltage is switched off at input K1-K2, the enable contacts open and the alarm contacts close after the set time has elapsed.

Check the set time following installation. For PSR applications, only yellow PSR-TBUS connectors (Order No. 2890425) may be used. Connection with another T-BUS is not permitted. Devices may only be mounted on/removed from the T-BUS when the power is switched off. A T-BUS unit can contain a basic device (PSR-...-SDC...) and a maximum of 10 extension units (PSR-...-UR...). Extension units must be mounted to the right of the basic device. The feedback circuit must be closed at the last extension unit (on the right): jumper at Y1 and 12 or PSR-TBUS-TP dummy plug (Order No. 2981716). The voltage supply can be provided at any PSR device or using a system power supply unit via the T-BUS. When using T-BUS DIN rail connectors, connect together the required number of T-BUS connectors and push them onto the DIN rail. When attaching the safety relay to the DIN rail, ensure that it is aligned correctly with the T-BUS connector (see Figure 4). ) D PSR-TBUS * + 3 Figure 4 Using the T-BUS DIN rail connector In order to comply with UL approval, use copper cables that are designed for operating temperatures > 75°C.
