Description

BENTLY  3500/32  4-channel relay module

Functional features: It is a full-height module, providing four relay outputs. Each output can be independently programmed to execute the voting logic. The relay contains the alarm drive logic, which is programmed through 3500 rack configuration software and uses AND, OR logic. It can utilize alarm inputs (alarm and dangerous states), “uncertain”, or a single PPL from any monitoring channel or their combination.
Electrical characteristics:
Power consumption: Typical value 5.8 watts.
Relay type: Single-pole double-throw (SPDT) relay. Two SPDT relays can be connected in one double-pole double-throw (DPDT) form.
Arc suppressor: 250Vrms, epoxy resin sealed, standard installation.
Contact life: 100,000 cycles @5A, 24Vdc or 240Vac.
Operation: Each relay of the four channels can be selected as either normally off or normally on through a switch.

Communication and Instructions:
OK LED: It lights up when the module is working properly.
TX/RX LED: Flashing indicates that the communication between this module and other modules in the rack is normal.
CH ALARM LED: It lights up when the relay channel is in the alarm state.
Environmental characteristics:
Operating temperature: -30°C to + 65°C (-22°F to + 150°F).
Storage temperature: -40°C to + 85°C (-40°F to + 185°F).
Humidity: 95%, no condensation.

Others:
A 3500/22 Transient Data Interface (TDI) module is required, as well as 3500 rack configuration software version 4.5 or higher, 3500 data acquisition software version 2.40 or higher, and 3500 data display software version 1.40 or higher.
When used with the 3500/93 LCD display module, the 3500/93 requires firmware version P or higher. When used with the 3500/94 VGA display module, the 3500/94 requires firmware version C or higher.
