The relays are designed for U-bar or flush mounting. They have terminals accessible from the front and include LED indication of operating conditions.

• Different versions for all JOLA sensors
• time relays
• control relays for A/D; U/I; frequency and levels
• programmable relays including add-on modules
• front terminals
• LED signalling
• also for explosive environments
