Description
The 3500/61 module provides six channels of temperature monitoring and accepts both Resistance Temperature Detector (RTD) and Thermocouple (TC) temperature inputs. The modules condition these inputs and compare them against user-programmable alarm setpoints.
Environmental Limits • Operating Temperature: ◦ -30°C to +65°C (-22°F to +150°F) when used with Internal/External Termination I/O Modules ◦ 0°C to +65°C (32°F to +150°F) when used with Internal Barrier I/O Modules (Internal Termination) • Storage Temperature: -40°C to +85°C (-40°F to +185°F)
Technical Specifications
Number of channels: 4 independent relay output channels
Relay type: Two single-pole double-throw (SPDT) relays are connected together to form a double-pole double-throw (DPDT) configuration
Contact rating:
Arcing condition: 250Vrms (standard installation)
Contact life: 100,000 times @ 5A, 24Vdc or 120Vdc
Alarm driving logic: Supports AND and OR logic programming, and can use alarm input (alarm and dangerous state), “uncertain” or a single PPL from any monitoring channel or any combination of monitoring channels on the rack
Programming settings: Achieved through the 3500 rack configuration software
Front panel indicator lights:
OK LED: The module flashes when it is working properly
TX/RX LED: Used for transmission and reception, it flashes when the module communicates normally with other modules in the frame
CH ALARM LED: Flashes when the relay channel is in an alarm state
Power consumption: Generally 6 watts
Operating temperature: -30°C to +65°C
Storage temperature: -40°C to +85°C
Humidity: 95% (non-condensing)
Installation method: Insertion design, easy to install and replace
Occupied slot: Occupies one slot
Product Features and Advantages
High Reliability: Designed in accordance with high-reliability industrial standards, suitable for long-term operation in harsh environments.
Flexible Configuration: Each output can be independently programmed to execute voting logic, meeting different application requirements.
Easy Integration: Compatible with the 3500 framework and other modules, facilitating integration into the Bently Nevada mechanical protection system.
User Friendly: Built-in LED indicators for displaying the status of each channel (activated or not activated), facilitating user monitoring and maintenance.
