Siemens 5WG1605-4DB23, RL 605D23

• For control of electrothermal valve drives for AC 24...230 V in heating/cooling systems via 2 noiseless semiconductor outputs

• With electronic protection of the outputs against short circuit and overload

• Rated current: 0.45 A per channel

• Max. inrush current (2 sec.): 2.75 A per channel

• Max. inrush current (2 min.): 0.75 A per channel

• Maintenance-free terminals for connection and through-wiring of untreated single-core, stranded or multi-core conductors, 0.5 ... 2.5 mm²

• 2 terminals per channel for connecting the electrothermal valve drives

• 2 terminals on the unit for supply of the valve voltage AC 24...230 V

• Bus-powered electronics

• Housing: plastic

• Built-in device for mounting in a separately to be ordered Control Module Box AP 118 or Room Control Box AP 641

• Type of protection: IP 20

• Per channel setting of the valve operation direction de-energised open or closed

• Per channel optional control via switching commands or continuous positioning commands

• Per channel control value limitation and adjustment of the valve characteristic for continuous control values

• Per channel control value monitoring

• Adjustable behaviour in case of override (lock, service mode, forced position, forced control)

• Per output automatic, demand-oriented or manual valve rinsing

• Per output operating hours counting and switching cycle counting with limit value monitoring

• Evaluation of the control values for heating or cooling demand requirements on a primary system and for controlling heating or cooling circuit pumps

• 2 room temperature controllers for 2-pipe or 4-pipe systems, adjustable as 2-position control or continuous control, for heating-only mode, cooling-only mode, heating and cooling mode, with two-stage heating or cooling

• Output of the control values optionally as switching command On/Off or as continuous control command

• 5 min., max. and weighted value calculators

• 6 logical operations (AND/OR/XOR/TRIGGER/LOCK)

• Surveillance of device function
