Approval Parameters

2.2.1. Intrinsically Safe Current Loop Interface
The ACM500 intrinsically safe current loop interface is approved using the entity value method of
evaluation. The entity parameters for each ACM500 approval can be found in the following sections
and also in the approval certificates in Appendix A. Refer to the approval documentation of the device to be connected to the ACM500 for its entity parameters.
The following conditions must be met. Note that the input values on the left side of the equations
below (U
As an alternative to the direct Inductance calculation, the following inductance to resistance formula
may be substituted:
2.2.2. Fiber Optic Interface
The ACM500 fiber optic interface is approved by limiting the maximum power applied to the fiber
optic cable. The power is restricted by design to 5mW maximum. This restriction is shown in the
approval certificates and control drawings in the Appendix.
