Introductions
Features
TRP-C28 provides 4 optical isolated digital input channels that allow you to input the logic signal from 0
to 30V DC and 4 power relays output . All channel features screw terminals for the convenience
connection of field signals as well as LED to indicate channel status. Each output power relay equips with
high surge current suppressors varistor to entirely protect your module and devices without damage when
irregularly high power voltage input. TRP-C28 can be configured and conduct self-test by outside dip-
switch without complicated setting and connection. Build-in a full set of command, watch-dog, auto reset
function the module can be bi-directionally remote controlled by RS485 protocol.
¾Wide range power input from +18V to +30V DC.
¾All communication's command are perform in ASCII.
¾Programmable in virtually any high-level language.
¾4-CH isolated digital input (with common power) and 4- CH power relay output.
¾Baud Rate can be set from 1200 to 115.2K bps.
¾High surge current suppressors varistor for relay.
¾LED display to indicate input and relay output channels and PWR/watchdog/RS485 status.
¾Dual Watchdog for hardware reset circuit and host operating status .
¾External switch for hardware self-test and module’s configuration.
¾Digital Input Isolation with power source (2500 Vrms).
¾Support screw terminal and standard external DC power adaptor.

1.Calculate all characters of the command string to get the ASCII sum, except the character return.
2.Mask the sum of string with 0FFH.
Example :
Send the command is “$06M”.
Sum of string is “$”+”0”+”6”+”M”=“24H”+”30H”+” 4D“=“A1H”……The checksum and [CHK]=“A1”.
Response string with checksum is :” A1 “.
How To Calculate The Checksum
Default setting:ID Address :01 Baud Rate:9600 DIO Mode Type :40 Checksum:Disable
Command Format :”Leading Code”+”ID Address”+”Command”+”CHK”+(cr) .
Response Format :”Leading Code”+”ID Address”+”Data”+”CHK”+(cr) .

Safe mode: Digital output when Watchdog enable.
Power on mode: Digital output when power on.
Watchdog: The watchdog is designed to monitor the module's output status to prevent the module
from communication problem or system halt due to unexpected situation
*User can save the module output value by using the command "ID5V" if the power is fails.
