The 1756-L7SP module is a dedicated safety partner controller. It pairs exclusively with GuardLogix L7S primary controllers. This partnership forms a redundant 1oo2 architecture for critical safety applications. You must install it in the slot immediately to the right of the primary processor. Consequently, this setup meets the demands of high-integrity systems.
This module has a power dissipation of just 2.5 W. Its thermal dissipation is rated at 8.5 BTU/hr. The backplane current draw is 800 mA at 5.1V DC. Additionally, it draws only 5 mA at 1.2V DC. The isolation voltage is 30V continuous with basic insulation. Furthermore, the USB port is tested at 980V AC for 60 seconds. The 1756-L7SP does not have its own user memory. Instead, it mirrors the memory of its paired primary controller. This design simplifies the system architecture. It is compatible with several primary models. These include the 1756-L71S, 1756-L72S, 1756-L73S, and their 'K' variants like the 1756-L71SK and 1756-L72SK. For energy storage, it works with the 1756-SPESMNSE capacitor module.
The operating temperature ranges from 0 °C to +60 °C. Meanwhile, the storage temperature is between -40 °C and +85 °C. The relative humidity must be 5-95% non-condensing. This controller also withstands operational vibration of 2G at 10-500 Hz. Moreover, it has a shock rating of 30G. It carries a T4A temperature code for North America. Similarly, it holds ATEX and IECx T4 temperature codes.
First, ensure the primary controller is installed in the chassis. Next, you must install the 1756-L7SP in the slot directly to its right. This physical placement is mandatory for the 1oo2 safety pairing. The module fits any 1756 chassis. For instance, compatible chassis include the 1756-A4, 1756-A7, 1756-A10, and 1756-A13. Likewise, standard power supplies like the 1756-PA75 and 1756-PB75 support this module.
This safety partner supports standard safety communication protocols. Specifically, it uses EtherNet/IP, DeviceNet, and ControlNet. You can program it using several languages. For example, it supports Relay Ladder Logic (RLL). Additionally, you may use Structured Text (ST) and Sequential Function Chart (SFC). These options provide flexibility for various engineering preferences.

1. Can the 1756-L7SP operate as a standalone controller?
No, the 1756-L7SP is a safety partner only. It must be paired with a primary GuardLogix L7S controller like the 1756-L71S or 1756-L73S to function.
2. What happens if the primary controller fails?
The 1756-L7SP continuously monitors the primary controller. In a failure event, the safety partner ensures the system transitions to a safe state as part of the 1oo2 architecture.
3. Which chassis are compatible with this module?
It fits all standard 1756 ControlLogix chassis. Examples include the 1756-A4, 1756-A7, 1756-A10, and 1756-A13 models.
4. Does this module require a specific power supply?
It works with standard GuardLogix power supplies. Compatible models include the 1756-PA75 and 1756-PB75, among others listed in the technical documentation.
5. Is programming software included with the module?
No, the 1756-L7SP does not include software. You need Rockwell Automation's Studio 5000 Logix Designer application with the appropriate safety add-on profile.
