BENTLY 3500-33 16-Channel Relay Module
BENTLY 3500-33 16-Channel Relay Module
Description
The 3500/33 16-Channel Relay Module is a full-height module that provides 16 relay outputs. You can place any number of 16-channel relay modules in any of the slots to the right of the Transient Data Interface (TDI) Module. Each output of the 3500/33 16-Channel Relay Module can be independently programmed to perform voting logic.
Each relay of the module includes Alarm Drive Logic. Programming for the Alarm Drive Logic uses AND and OR logic and may use the following:
· Alarming inputs (alert and danger statuses)
· Not-OK
· Individual Measured Variables from any monitor channel or any combination of monitor channels in the rack

Ordering Considerations
· The 3500/33 16-Channel Relay Module requires the 3500 Rack Config, version 3.3 or later.
·The 3500/33 requires the 3500 Data Acquisition Software, version 2.40 or later.
· The 3500/33 16-Channel Relay Module requires the 3500 Data Display Software, version 1.40 or later.
· When ordered with the multiple approvals option (02), the 3500 monitor is certified to Zone 2 standards, including ATEX and North American zones.
· The Zone 2 standards specify increased spacing requirements at higher voltages. The 3500/33 16-Channel Relay Module does not meet these spacing requirements. Thus, the module ordered with the multiple approvals option is limited to a lower voltage than those with the other approvals options.
· Using higher voltages violates the hazardous area certificates associated with the multiple approvals option.
· The North American Division 2 standards associated with the CSA-only approvals option (-01) have been de-rated to 30 Vrms to comply with 61010-1 type test requirements.
· If the 3500/3316-Channel Relay Module is part of a functional safety (SIL) system, the functional safety certificate requires the restricted voltage. Higher voltages are not allowed for functional safety (SIL) systems.
IO module has the following main functions
Input Function
The IO module can receive input signals sent by external devices and convert them into digital or analogue signals for use by the computer system or control system. These input signals can come from a variety of sensors, such as temperature sensors, pressure sensors, photosensitive sensors and so on. By receiving and parsing these input signals, the system can monitor and control the external environment in real time.
Output Functions
The IO module is capable of converting the output signals generated by a computer system or control system into the form required by an external device. These output signals are typically used to control actuators such as motors, valves, lights, etc. By sending appropriate output signals to external devices, the system enables control and operation of the external environment.
Data Acquisition and Processing
The IO module is capable of acquiring data from external devices and transferring it to a computer system or control system for further processing. This enables the system to acquire environmental data, status information and user inputs in real time and make appropriate decisions or perform specific tasks based on this data.
