What this part is: Siemens RMZ787 universal expansion module for Synco 700 HVAC controllers. Manufacturer: Siemens. Part Number: RMZ787. Product Type: input/output extension module. Universal Inputs: 4. Digital Outputs: 4, relay. Power Consumption: 3 VA. Supply: taken directly from the host controller module. Protection Rating: IP20. Controller Platform: Siemens Synco 700 family. Decoding the designation: RM — the Siemens designation block for Synco 700 heating, ventilation and air-conditioning controllers. Z — the accessory and extension-module position in that block. 787 — the execution number fixing the 4 universal input, 4 digital output version. RMZ785, RMZ788 and RMZ789 are the other module types in the same family. What these specs mean in practice: Universal Inputs: 4, each independently configurable. The accepted signal types are 0 to 1000 ohm, 1000 to 1175 ohm, DC 0 to 10 V, potential-free contact, LG-Ni 1000, Pt1000, T1 (PTC) and 2 x LG-Ni 1000. One module therefore reads temperature sensors, pressure transmitters and switch contacts side by side, with the type set per channel in software rather than by a link or a different card. Digital Outputs: 4, relay. Relay contacts switch valve actuators, damper motors, pumps and fan starters directly. Power Consumption: 3 VA, taken from the host controller. The module draws its supply over the connection to the Synco 700 controller, so a panel needs no additional transformer for it. Protection Rating: IP20. Suited to a mounted enclosure or a control panel. Mounting data: Mounting Type: attaches to the Synco 700 controller module. Protection Rating: IP20. Quantity and configuration: Unit Quantity: 1 Pc. The listing is for one module. Interchange guidance: MPN Variants: RMZ787, RMZ-787, RMZ 787. Related modules in the same family carry different input and output complements: RMZ785, RMZ788 and RMZ789. The 787 is the 4 universal input, 4 relay output execution.
