TCW242-S_R1.0 – July 2021 Page 15
Example:
For humidity sensor HIH-4000-003 the following parameter (coming from datasheet) should
be set for fine work:
Multiplier - 31.74
Offset - 0.826
Mode - 0-10V
Unit - %RH (is set in the channels web page)
The value of the multiplier is inverted of slope parameter (1/0.0315);
If the output voltage of this sensor is 3.198V the value of analog input will be 75.28% RH:
75.28 = (3.198 – 0.826) * 31.74
8.2.3.2. Digital inputs
TCW242-S has 4 digital inputs. All they are isolated from the power supply but use the same
ground. Every digital input can work in OPEN/CLOSE or COUNTER mode. In COUNTER mode,
counting can be made on rising, falling, or both edges.
For the counter mode, there is a possibility for setting up the counter initial value.
There are two delays – Open-to Close and Close-to-Open. The delays are in the range of 5 to
60000mS. These delays can be used for additional digital filtering. The delays are applied in
both modes.
In the picture above Open-to Close and Close-to-Open delays are set to 13mS.
8.2.3.3. Relay outputs
Each relay can be activated either remotely by the WEB interface, HTTP API, and SNMP or locally,
from the alarm conditions.
For WEB control every relay has “On”, “Off” and “Pulse” buttons. There are also “All On”, “All
Off” and “Pulse All” for common control of relays. Pulse duration in seconds can be set
separately for each relay in “Setup-Input/Output-Relay Outputs”.
