About 1734-IB8S

The 1734-IB8S is a POINT Guard I/O safety Discrete Input Module. This module is used with the POINT I/O product family for implementing Common Industrial Protocol (CIP) safety protocol extension implemented over Ethernet I/P and DeviceNet communication protocol. Through these protocol and connections, safety messages can be transferred. It is not compatible with 1734-ADN, 1734-ADNX, 1734-APB, and 1734-ACNR communication adapters. This module features Eight (8) Current Sinking inputs with a ON state input of 11-30V at 3.5 mA DC and reaction time of less than 16.2 ms. It also has Four (4) Current Sourcing Pulse Test Outputs with T0, T1M, T2 and T3M output sources. This safety module is available in series A and Series B. With Series A, the module consumes current of 175 mA while Series B has current consumption of 110 mA. Series A tends to dissipate more heat thus, it is recommended to use termination modules particularly 1734-CTM or the Common Terminal Module. Series B modules are designed with less heat dissipation thus CTM modules are not recommended unless required by the control system design. Series B module cannot be used to replace a Series A module in a plug and play manner. Similarly, a Series A module cannot do the same plug and play replacement. EDS files must be loaded to these module to be recognized in the network. The 1734-IB8S features compatibility with safety devices such as gate switches, Emergency Stop Pushbuttons, light curtains and similar devices. It has Single channel mode that is used to evaluate an input signal per channel, allowing the module to be used in Safety Category 2 and in applications rated up to including performance Level d / SIL CL2. In this mode, the channelÕs Point Mode configuration is set to Safety Pulse Test. It also has Dual channel mode used for evaluation of consistency between Two (2) channels. This mode allows the module to be used in application that are rated up to including Level e / SIL CL3. Both channel modes must be set to Safety Pulse Test when this mode is utilized. User may also configure discrepancy time for controlling the allowable discrepancy between each channel before a fault is detected. Input channels also have individually adjustable ON and OFF delays for each channel. Test Outputs are configurable for digital input modes only. The 1734-IB8S is provided with separate test outputs for detecting short circuit of a safety input. These test outputs may also be configured as standard outputs for use in general applications. The module is also provided with specific test outputs for broken-wire detection of a muting lamp. For DeviceNet network, RSNetworx for DeviceNet version 9 is required. It may also be used with Studio 5000 Environment Version 21.00 or higher.
