Input Modules
Input modules support a single electrical type, such as digital or universal inputs. The available input modules include the following:
DI-16
UI-16
RTD-DI-16
DI-16 I/O Module
The DI-16 I/O module is a digital input, 16-channel I/O module. You can use the DI-16 I/O module for sensing of multiple dry digital inputs in applications such as equipment status or alarm point monitoring.
The maximum counter frequency is 25 Hz on all sixteen inputs. This input type is useful in metering applications.
The following input types are supported:
Digital input
Dry contact, Open Collector, or Open Drain
For more information, see DI-16 I/O Module .
UI-16 I/O Module
UI-16 is a 16-channel universal input module with status indicators for each of the inputs. You can use this module for any mix of temperature, pressure, flow, status points, and similar inputs in a control system with a 0-10 V input range and a 12-bit A/D conversion. You can also make adjustments for various sensor types using the available pull-up resistors.
The following input types are supported:
Dry contact closing
Voltage 0–10 V
Current 0–20 mA
Thermistor– 10k Type I (Continuum), 10k Type II (I/NET), 10k Type III (Satchwell), 10k Linearized (Satchwell D?T), 10k Type IV (FD), and 10k Type V (FD w/ 11k shunt)
Thermistor– 1.8k (Xenta)
Thermistor– 1k (Balco)
Thermistor- 20k (Honeywell)
Thermistor- 2.2k (Johnson Controls)

RTD-DI-16 I/O Module
A Resistance Temperature Detector (RTD) is a sensing element that uses the change in the resistance of a metal, such as platinum or nickel, to measure temperature ranges from -50C to 150C. Due to their accuracy and repeatability, RTDs are used in scientific and industrial applications to measure temperature for kilns, gas turbine exhaust, diesel engines, and other industrial processes as well as for room temperature measurement.
In Building Operation, the RTD-DI-16 is a 16-channel I/O module with 1 return per 2 inputs. It supports the following input types:
RTD Temperature including:
Pt100
Pt1000
Ni1000
LG-Ni1000
RTD Resistance including:
100 ohms
1,000 ohms
Resistance including 0 to 15,000 ohms
Digital
Counter
The RTD connection type is either a 2-wire or 3-wire configuration with a 3-wire RTD using 2 inputs. For more information, see RTD-DI-16 I/O Module .
