Crestron part number ZUMLINK-DIN-IO
The Crestron ZUMLINK-DIN-IO is a DIN rail integration module with a standalone timeclock for Zum wired lighting. It applies schedules, events and common integration protocols to a Zum space without a control system, and gives a room level interface to third-party controllers such as HVAC/VAV systems and shade controllers.

About the Crestron ZUMLINK-DIN-IO
The module provides a standalone astronomical time clock with local time and date settings, so a Zum space can run schedules and events without a ZUM-HUB4 or a control system. A battery backs up the timeclock, with a stated backup life of 10 years. As a Zum Wired device it is discovered by the Zum app and configured there without custom programming.
For integration it has two relay outputs (C, NO, NC) rated 30 VAC/VDC at 1 A, two keypad inputs for input relays with keyswitch LED support, an RS-232 port (GND, TX, RX, RTS, CTS) and an RS-485 port (GND, D+, D-). These give a distributed, room level link to third-party smart controllers, such as HVAC/VAV systems and shade controllers.
It is powered from the Zum Link bus, drawing up to 80mA, and two RJ45 Zum Link ports daisy-chain it with other in-room Zum devices. The light grey polycarbonate housing mounts on DIN rail, 4 modules wide, and measures 94 mm high, 71 mm wide and 59 mm deep. Crestron rates the in-cabinet air temperature at 0° to 55°C.

It has two relay outputs (C, NO, NC) rated 30 VAC/VDC at 1 A, two keypad inputs with keyswitch LED support, a 5-pin RS-232 port (GND, TX, RX, RTS, CTS), a 3-pin RS-485 port (GND, D+, D-) and two RJ45 Zum Link ports for daisy-chaining.
How is the module powered?
It is powered by the Zum Link bus rather than its own power input, with a maximum current consumption of 80mA. Keypad feedback LED current of up to 20mA is passed through from the Zum Link bus.
How is the module mounted?
It mounts on DIN rail and takes 4 modules (4M) of width. The light grey polycarbonate housing measures 94 mm high, 71 mm wide and 59 mm deep and weighs 133 g, and Crestron rates the local in-cabinet air temperature at 0° to 55°C (32° to 131°F).
How much is the Crestron ZUMLINK-DIN-IO?
Crestron asks its dealers to give the price of the ZUMLINK-DIN-IO directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the ZUMLINK-DIN-IO?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the ZUMLINK-DIN-IO on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the ZUMLINK-DIN-IO come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the ZUMLINK-DIN-IO develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the ZUMLINK-DIN-IO in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the ZUMLINK-DIN-IO without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
