Dry contact expansion unit for Didactum remote monitoring systems
This CAN-Bus (Control Area Network) based extension unit has been specifically developed for the SNMP-enabled Didactum remote monitoring systems. As part of the general IT trend towards consolidation of infrastructures and operation centers into centralized based locations you can monitor all of your activity 24/7 through your network or Internet connections using the Didactum units 64 dry contacts. All of the alerts can then be sent directly to your on site technicians, or on to your central command center.
Typical applications are:
- TCP / IP integrations of relays / dry contacts
- Remote dry contact monitoring
- IP connection of HVAC systems and generators
- Integration of emergency power and ire alarm systems in TCP/IP networks
- Integration of building management systems in SNMP-compatible NMS
Up to 64 ports for IP connection of dry contacts
This extension unit for Dry Contacts oﬀers the user up to 64 inputs for the IP connection digital/ dry contacts. If a larger number of dry contacts are needed, simply connect additional expansion units. Up to 8 CAN-Bus devices can be connected to each of the 2 CAN-Bus Ports of your SNMPv1/v2c/v3 compliant Didactum remote monitoring device. The total length of each CAN-Bus port can be up to 300 meters / 1000 feet.
The installation of Didactum`s dry contact expansion unit is simple. Thanks to the CAN -Bus support Didactum IP alarm systems you can connect this unit to either of the two CAN-Bus ports. A 2 meter RJ12 patch cable is already included. For longer distances you can use your own patch cable.
Simply connect the dry contacts of your mission critical equipment, such as generators, UPS or HVAC systems, with a 2-wire signal cable.
Then login via the browser on Didactum`s embedded web server. Here you can easily configure each dry contact port. You can individually name each dry contact (UPS1, UPS2, generator3, aircon4, door switch3 and so on).
You can then set the normal state of the dry contact switch to NO = normally open or NC = normally closed. For each dry contact switch you can set individual types of actions or notifications.
For example, in the event of a failure of your business critical air conditioning systems you can specify that an SNMP trap has to be sent to the network management system (NMS) and that the technician / administrator must be alerted by SMS (GSM modem required). If desired, the SNMP-enabled Didactum monitoring system can also switch it`s integrated relays. All events of the dry contact inputs are stored in the syslog of TCP/IP based Didactum remote monitoring system. The syslog can be easily exported to HQ for further investigation.

32 - 64
|Mounting||The unit includes two 19" mounting angles for mounting inside the rack. Alternatively, there are 2 mounting holes on the bottom of the case for fastening on the wall. Fasten the unit, connect CAN inputs to the input of the previous CAN unit or of the monitoring unit. The red LED lights up. |
Match the bus terminators of the CAN units. Switch terminator TR in ON position on the monitoring unit and on the last CAN unit, TR on intermediate CAN units are in Off (1,2) position. Maximum 8 CAN units, sensors and/or devices can be on one CAN bus.
|Connection||To connect CAN units to the system, log into the interface -> Preferences -> Can Config -> CAN1 or CAN2 (depends on which physical port CAN1 or CAN2 of the system the unit is connected). |
Click Config button and wait. The system will poll the bus CAN and give rows with data, if successful will write: Done!. CAN modules and sensors will appear in the list. Click Apply and then click Restart.
Go to --> System Map / Floor Map, click Refresh button, or wait, new devices and new sensors will appear in the tree. Green LEDs on the CAN unit will light up when CAN unit is connected and successfully determined by the system.
Connection is not successful if after clicking Config, the poll is reset before the phrase "Updating". Check whether terminators on the bus line are set in the right position, change their position using TR switch if needed.
|Delivery||Unit, 3-pair shielded patch cable RJ-12 2 m length, screw 3.5 x 16 mm, fastener 2-sided, rubber feet, 19" mounting angles.|
