1 Data sheet S pulse counter with S-Bus interface The S-S-Bus coupler module is a device for the collection of S pulses. With this module the consumption data of any measurement device with a S output becomes bus capable and can be accessed by every Saia PCD or Energy Manager through the S-Bus. Main features: Up to S-S-Bus Modules on the same bus 4 S pulse inputs (S+... S4+) per S-S-Bus Module Up to 4 S devices on the same S-Bus The inputs comply with the S standard Integrated RS-485 termination resistor LED for bus activity indication Order number PCD7.H4SE Technical Data Protection type as DIN45 Operating voltage Un Current draw Power draw IP 4 connections IP 2 23 VAC (-2/+5%) < 2 ma < 3 W Temperature - Operation -25 C +55 C - Storage -25 C +7 C EMC / noise immunity Insulation characteristics LEDs - Surge voltage according to IEC6-4-5 on main electric circuit, 4 kv.2 / 5 μs - Surge voltage according to IEC6-4-5 at S inputs, kv.2/5 μs - Burst voltage according to IEC Main electric circuit 4 kv direct - S inputs 2 kv capacitive - S-Bus connections kv capacitive - ESD according to IEC6-4-2, - Contact 8 kv, air 8 kv - 4 kv / 5 Hz test according to VDE435-6 kv.2 / 5 μs surge voltage according to IEC Device protection class II - Run indication by green LED (On) - Function indication by red LED when bus active Mounting Mounting Connections On 35 mm DIN top-hat rail (EN522) any mounting position - For Pozidrive, Philips or slot-head screwdriver N - Sx, S-Bus, 23 VAC mm 2

Technical data S-Bus Bus system S-Bus Transmission rate The transmission Baud rate is automatically detected Transmission mode Data Bus length (max.) 2 m (without repeater) Response time: Write: 3 ms Read: 2 ms The communication is ready 3 s after the Power On For a description of the used Registers please look at the Register Page Data transmission Only «read/write» register instructions are recognized. Only one register can be written at a time. The device will respond «NAK» if more than register is written. Up to 2 Registers could be read at a time. The device will respond «NAK» if more than 2 registers are read. The device will not respond to any unknown query. The device has a voltage monitoring system. In case of voltage loss, registers are stored in EEPROM (transmission rate» etc.) Datasheet PCD7.H4SE S pulse counter with S-Bus interface 3
