RTD-DI-16
Introduction
SpaceLogic* RTD-DI-16 Central IO module is an RTD/digital input, 16-channel I/O module.
The inputs of RTD-DI-16 can be configured to read seven different types of inputs:
2-wire RTD temperature
3-wire RTD temperature
2-wire RTD resistive
3-wire RTD resistive
Digital
Counter
Resistive
RTD-DI-16 supports 3-wire configurations that consume two input channels. The number of channels available range between 8 to 16 depending on the number of 3-wire configurations that are used.
The inputs can be used for sensing multiple dry contact inputs in applications, such as equipment status monitoring or alarm point monitoring. As counter inputs, they are commonly used in energy metering applications.
The RTD inputs are ideal for temperature points in a building control system.
* Formerly known as SmartX.
Function
The modules are part of a modular system that delivers power and communications on a common bus. Connecting modules is a one-step process: just slide the modules together using the built-in connectors.
Each module can be separated from its terminal base to allow the site to be wired prior to the installation of the electronics. The patented locking mechanism serves as handles for removing the module from its base. All critical components have a protective cover that permits convection cooling to occur.
Because critical applications require 24-hour operation, Schneider Electric designed the Central IO modules for hot-connection of terminal bases and hot-swapping of the modules to their bases. This design ensures continuous power and communication during service operations.
The auto-addressing feature helps eliminating the need for setting DIP switches or pressing commission buttons. Each module automatically knows its order in the chain and assigns itself accordingly – significantly reducing engineering and maintenance time.
Fasteners easily snap into a locked position for panel installation. The fastener has a quick-release feature for easy DIN-rail removal.
The Central IO module terminals are clearly labeled and protected by transparent covers. The input and output terminals are at the top and bottom of each module and are accessible for maintenance without removing the module. The EcoStruxure Building Operation WorkStation software can generate custom as-built labels for each module. Pre-perforated letter and A4 size label sheets are available as an accessory.
The SpaceLogic devices use built-in connectors for single row connectivity, side by side. If a panel size requires multiple rows, extension cords are available.
The Central IO module has a status indicator that denotes the health and status of the module.
Each input channel has a dedicated two color status LED. The LED can be configured to display either red or green for each input state.
Protection components on the inputs protect against high-voltage short-duration transient events.

For protection from excess current that could be produced by field wiring, follow these instructions:
Connect one RET terminal on each of the Central IO modules to a common chassis/power ground rail in the control panel using a size 16 AWG (1.3 mm 2 ), or larger wire.
Individual 24 VDC power sources to the field must be current limited to maximum of 4 A for UL compliant installations, and no more than 6 A in other areas.
For more information on wiring, see the SpaceLogic Hardware Reference Guide.
