因此，3500/33继电器使用多 个批准选项订购历史上是否被限制在-个较低的水平电压比与另- 种排列的电压高批准的选择。使用更高的电压违反危险区域证书与多个批准选项关联。北美2区标准与CSA-only approvals选项相关联(-01)已降至30Vrms以配合符合61010-1型试验要求。如果3500/33是功能安全的一部分(SIL)系统， 功能安全证书需要限制电压。更高的电压不允许使用功能安全(SIL)系统。可以将现场接线连接到3500/33继电器这样的导体暴露于潜在的人类接触。这可能在高压下有触电危险。客户应只使用3500/33继电器电压高达30Vrms。适当的安全应采取预防措施电击的危险。

BENTLEY 149986-01 Relay Output Module, the Bentley 3500/33 Sixteen Channel Relay Module is a full height module that can provide an output of 16 relays. Any number of 16 channel relay modules can be placed in any slot on the right side of the frame interface module. Each output of the 16 channel relay module can be independently programmed to execute the required voting logic. Each relay applied to a 16 channel relay module has an “alarm drive logic”. This alarm driver logic can be programmed using “AND gate” and “OR gate” logic, and can utilize alarm inputs (warning or danger), non OK, or independent PPL provided by any monitor channel or combination of monitor channels in the framework. The alarm driven logic application framework configuration software programming can meet special needs in applications. 3500 monitors are certified as Zone 2 standards (including ATEX and North America) with the option of multiple order approval (-02). The Zone 2 standard specifies that increasing the spacing requirements at higher voltages does not meet these spacing requirements for 3500/33 relays.

Therefore, the use of multiple approval options for ordering 3500/33 relays has historically been limited to a lower horizontal voltage ratio compared to a higher approved option for another arrangement. The use of higher voltage violates the hazardous area certificate and is associated with multiple approval options. The North American Zone 2 standard is associated with the CSA only approvals option (-01) and has been reduced to 30Vrms to meet the requirements of the 61010-1 type test. If 3500/33 is a part of functional safety (SIL) system, the functional safety certificate needs to limit the voltage. Higher voltages do not allow the use of Functional Safety (SIL) systems. Field wiring can be connected to conductors such as 3500/33 relays that are exposed to potential human contact. This may pose a risk of electric shock under high voltage. Customers should only use 3500/33 relays with voltages up to 30Vrms. Appropriate safety measures should be taken to prevent the danger of electric shock.
