What power supply is required for the 2118-2?
The 2118-2 accepts 115 or 230 V AC, 50-60 Hz. Refer to the voltage selector switch on the side of the unit. Power consumption is less than 10 VA.
How can I change the output range from 0-10V to 4-20mA?
Locate the output jumpers inside the module. Set them to the desired output type. Refer to the manual for jumper positions. After changing, recalibrate if necessary.
What is the calibration interval for the 2118-2?
Daytronic recommends annual calibration to maintain specified accuracy. Calibration can be performed by an accredited lab or returned to Daytronic.
Can I use the 2118-2 with a PT100 RTD?
Yes, the 2118-2 supports PT100 RTDs in 2-wire, 3-wire, or 4-wire configurations. Select the appropriate input range and connect accordingly.
The output reading is unstable. What should I check?
Check for loose connections, electrical noise from nearby equipment, or improper grounding. Ensure the input signal is within range and the sensor is properly shielded. If problem persists, contact Daytronic support.
How do I mount the 2118-2 on a DIN rail?
Attach the DIN rail mounting bracket (included) to the back of the module. Snap the module onto a standard 35 mm DIN rail. For panel mount, use the screws provided.
Is the 2118-2 suitable for outdoor use?
The 2118-2 is designed for indoor use only. It should be installed in a dry, sheltered environment with ambient temperature between 0°C and 60°C. Avoid direct sunlight and moisture.
What is the maximum wire length for inputs?
For voltage inputs, keep wire length under 100 meters to minimize noise. For 4-20 mA loops, up to 1000 meters is possible. For thermocouples, use appropriate extension wire and limit to 50 meters.
