STBPDT3100K - STB Standard Power Distribution Kit, 24 V DC, with Base and Terminals

Product type: Power Distribution Kit  |  Range: Modicon STB  |  Supply: 24 V DC  |  Output: 10 A  |  Kit: module + base + screw and spring connectors

The STBPDT3100K is the standard power distribution kit of the Modicon STB distributed I/O island. It takes the 24 V DC field supply and distributes it on the island bus to two separate circuits, the sensor bus (IN) and the actuator bus (OUT), so that input and output modules can be protected and isolated from each other. The kit is supplied complete: the STBPDT3100 module, the STBXBA2200 mounting base, one set of STBXTS1130 screw type connectors and one set of STBXTS2130 spring type connectors. Only one of the two connector sets is used in a given island, so either screw or spring wiring is possible without ordering anything else. The module is 125 mm high, 18.4 mm wide and 65.1 mm deep, has a white housing and takes 18.4 mm of width on the 35 mm DIN rail.

The rated supply voltage is 24 V DC and the working range on the sensor and actuator bus is 19.2 to 30 V DC. The output current for the input/output circuit is 10 A; the datasheet also lists 12 A, 8 A and 6 A ratings for other circuit arrangements, 0 to 4 A for the input circuit and 0 to 8 A for the output circuit. Protection is built in: overcurrent protection with a 10 A time-lag fuse on the output circuit and a 5 A time-lag fuse on the input circuit, plus reverse polarity protection on the actuator bus. The grounding terminal withstands a permissible current of 30 A for 2 minutes, and the overvoltage category is II.

Two green LEDs on the front panel report the supply state: one for the actuator bus power supply (OUT) and one for the sensor bus power supply (IN), so loss of either circuit is visible at the module without a meter. According to the product datasheet, hot swapping is not supported on this module (hot swapping fallback: No), so the island should be powered down before the module is removed or replaced.

The kit is built for an STB island mounted on a 35 mm DIN rail: operating temperature 0 to 60 °C without derating, storage temperature −40 to 85 °C, relative humidity 95 % at 60 °C without condensation, operating altitude up to 2000 m and pollution degree 2. Vibration resistance is 3 gn and 5 gn over 58 to 150 Hz on the 35 mm DIN rail with 0.35 mm amplitude from 10 to 58 Hz, and shock resistance is 30 gn for 11 ms. Protection degree is IP20. The product is marked CE and certified CSA, UL and FM Class 1 Division 2, and conforms to EN/IEC 61131-2 type 1.

Net weight is 0.13 kg. One kit is packed in a 14 x 8.5 x 2.5 cm carton of 150 g, and the contractual warranty is 18 months. Because the K reference is a kit and not a bare module, check the kit composition before comparing it with the STBPDT3100 module alone.
