Inputs
Digital Inputs
12 digital active-low inputs with pull-up resistors.
ON voltage level: 0-0.8 V
OFF voltage level: 3.75V to +BAT
Input resistance: more than 5 k
Ω
(10k
Ω
pullup to +5Vdc)
The inputs have internal over and under voltage protection.
References
Four DGND references for inputs are provided
Outputs
Relay Outputs
8 Form C relay outputs.
Resistive load:
2 A (NO)/2 A (NC) at 125 VAC
2 A (NO)/2 A (NC) at 30 VDC
Dielectric strength:
4,000 VAC, 50/60 Hz for 1 min between coil and contacts
750 VAC, 50/60 Hz for 1 min between contacts of same polarity
There is no special overcurrent/overvoltage protection on the relay outputs. The user is
advised to provide a fast acting 3A fuse or an adequate external protection if necessary.
Indicator
Front panel Red-Green LED indicator. (See Table 1)
Communication
CAN
1 CAN 2.0B port, protocol CiA CANopen ®
Default baud rate 125 kbps, default Node-ID 127
By default, the DIO128 Controller transmits DI Read State 8-bit (6000h) and DO Read State
8-bit (2200h) on TPDO1
Network Termination
According to the CAN standard, it is necessary to terminate the network with external
termination resistors. The resistors are 120 Ohm, 0.25W minimum, metal film or similar
type. They should be placed between CAN_H and CAN_L terminals at both ends of the
network.
