Epec (Finland) has released the 3720 and 3610 control units featuring multiple CAN ports. The products support CANopen and are for outdoor applications.
The Epec 3720 can control ten proportional valve pairs. The I/O interface is compatible with the predecessor, the Epec 2020. The control unit comes in the same ruggedized aluminum housing and connectors. However, the 3720 unit comes in a new look and without product codes. It features a 1-MiB RAM for application parameters and an 8-KiB FRAM for configuration parameters. There are versions with and without internal CAN termination available.
Already in summer, the Finish company has launched the 3610 controller, which is I/O compatible with the predecessor 2038. Besides two CAN interface, it also features an EIA-232 port. The product provides a high-side current measurement and an internal 3-axis accelerometer for leveling purposes, for example. The control unit features optionally a Pt1000 measurement.
Both control devices implement Codesys 2.3 and are programmable in IEC 6113-3 languages. The firmware supports pulse inputs. Another add-on feature is the possibility to remove customer applications using the product’s BSL pin. The operating range is -40 °C to +85 °C. At the Agritechnica 2017 tradeshow in Hanover (Germany), these controllers are exhibited.
