Information About 1756-M08SE

The Allen-Bradley 1756-M08SE is a ControlLogix module. It is a Serial Real-time Communications System (SERCOS) interface module that is used to enable a ControlLogix rack to directly interface with SERCOS drives.

The 1756-M08SE supports integration of up to Eight (8) Kinetix drives, compatible with a variety of drives from different Kinetix series such as 2093 Kinetix 2000 multi-axis servo drive, 2094 Kinetix 6000 multi-axis servo drive, 2099 Kinetix 7000 high-power servo drive and 2098 Ultra3000 SERCOS servo drive. The 1756-M08SE is able to perform data exchange with speed of 4 Mbps and 8 Mbps and cycle times, depending on the data rate and number of connected drives. At 4 Mbps data rate, cycle times include 0.5 ms, up to 2 drives; 1 ms, up to 4 drives and 2 ms, up to 8 drives while at 8 Mbps, cycle times are 0.5 ms, up to 4 drives; 1 ms, up to 8 drives and 2 ms, up to 16 drives. This SERCOS can be configured to implement different drive control modes such as Position, velocity, and torque.

The 1756-M08SE is directly installed to a 1756 ControlLogix chassis. Compatible chassis are 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 along Standard and redundant power supplies such as 1756-PA72/C, 1756-PA75/B, 1756-PB72/C, 1756-PB75/B, 1756-PC75/B, 1756-PH75/B and 1756-PA75R, 1756-PB75R, 1756-PSCA2, respectively.

Compatible physical media for high-speed communication of the SERCOS drive are Plastic-Fiber Optic cables with catalog numbers 2090-SCEPxx-0 non-jacketed, chlorinated polyethylene 2090-SCVPxx-0 standard jacket, polyvinyl chloride 2090-SCNPxx-0 nylon jacket and 2090-SCVGxx-0 standard jacket, polyvinyl chloride Glass fiber optic cables.

Compatible ControlLogix chassis include the 1756-A4, 1756-A7, 1756-A10, 1756-A13, and the 1756-A17. The 1756-M08SE module has an open-type enclosure. The 1756-M08SE module allows you to control the drives in position, velocity, and torque modes. This module supports reliable noise immunity and high-speed data transmission. It also supports ASA messages converted to a SERCOS format, and does not need interconnected wiring. Two SERCOS data rates are available for this module, namely 4 Mbps and 8 Mbps. At 4 Mbps, the SERCOS cycle time is 0.5 ms for up to 2 drives (but only the Kinetix 6000 drives lets you use a 0.5 ms cycle time), 1 ms for up to 4 drives, and 2 ms for up to 8 drives. The SERCOS cycle time at 8 Mbps is 0.5 ms for up to 4 drives (but also only for Kinetix 6000 drives), 1 ms for up to 8 drives, and 2 ms for up to 16 drives. This module has a current draw of 760 mA at 5.1V DC and 2.5 mA at 24V DC. It has a power dissipation of 5 W, a non-condensing relative humidity of 5% to 95%, a vibration of 2 g at 10 to 500 Hz, an operating shock of 30 g, and a non-operating shock of 50 g. Its operational temperature range is between 0 to 60 degrees Celsius and the storage temperature range is between -40 to 85 degrees Celsius.
